I have a typical Edit here of a 2 min film with some video layers and some graphics where I also use MOGRTs. Now i obeserve the following: I duplicate this sequence (right click -> duplicate). BUT the new sequence is NOT identical with the original. There are elements (manly graphic elements) of an older version of this edit inside. Must be a clear bug. Because when I duplicate a sequence I expect it to be identical. Please look into this. I am on Premiere 14.6. on an iMac Pro with Catalina 10.15.7
